# Unreal Engine 5.4 → 5.5 migration checklist

Use Epic’s official release notes and migration guides as the source of truth.

## Core steps

1. Back up the project and work on a copy — do not rename the engine folder in-place as your only migration step.
2. After plugin or content path changes, run “Fix Up Redirectors” on relevant folders and resave affected maps.
3. Rebuild DDC and lighting if you change renderer, world partition cells, or large lighting setups (can take hours on big projects).
4. Smoke-test PIE, packaged build, and target platforms you ship (desktop + mobile/console as applicable).

## Upgrade-specific

- [ ] Read Epic’s **5.4 → 5.5** breaking changes / deprecation list for your modules.
- [ ] Recompile C++ modules; fix API breaks and replace deprecated headers/macros.
- [ ] Update third-party plugins and binaries to builds targeting **5.5**.
- [ ] Diff project settings (.ini), default maps, and packaging profiles after conversion.
